Western larch grows in valleys and on the lower slopes of mountains in the southern Interior of British Columbia. As it is intolerant to shade it does well in open stands. This large tree can grow to 80 metres tall and metres in diameter. Western larch usually grows in mixed stands with Douglas-fir, western hemlock and lodgepole pine. IMMEDIATE FIRE EFFECT ON PLANT: Mature western larch are able to withstand most fires; poles may survive low to moderate fires [30,].Although young trees may survive high temperatures for a short time, thin-barked seedlings and saplings are readily killed by fire [19,33,,,].Bark thickness, crown function, and tree vigor, as well as the .
Larch has a characteristic where is splits vertically easily. Made great fence rails and shakes for roofing. Interestingly, it is a preferred tree to leave in thinning stands throughout the Western US because the trees needles do not want to burn as readily as most of the other species around it. Canadian Journal of Forest Research, , 39(3): , although not always, greater than growth in stands treated with thinning from below. However, the differences in growth between thinning methods are smallest at stocking levels and stand ages typical for red pine management. Growth and yield of western larch in response to Cited by:
Individual western larch can live years, but ancient trees are extremely rare, Pass said. Most of the old-growth western larch was logged a century ago for its valuable timber. Western Larch is also known as Mountain Larch, Western Tamarack, Hackmatack UNIQUE FEATURES: Western Larchcan grow for up to years.

From the results of this study, crop-tree thinnings by the D+4 or Crown Rules are not recommended for overstocked year-old western larch stands, unless other resources benefit enough to offset the disappointing crop-tree growth response of the thinned stand.
Instead, low thinning is recommended, preferably when the stand is younger. Get this from a library. Crop-tree thinning a year-old western larch stand: year results. [Dennis M Cole; Intermountain Forest and Range Experiment Station (Ogden, Utah)].
Western larch grows best in the cool climates of mountain slopes and valleys on deep porous soils that may be grav-elly, sandy, or loamy in texture. The largest trees grow in western Montana and northern Idaho. Western larch characteristically occu-pies northerly exposures, valley bot-toms, benches, and rolling topography.
Cubic volume growth and tree vigor of year-old western larch (Larix occidentalis) with and without dwarf mistletoe (Arceuthobium laricis) were measured 15 years after thinning.

western larch, simple thinning of a late seral stand to reduce competition or crown. Western Larch Tree Western Larch (Larix occidentalis, Nutt.)-A pyramidal tree, with naked trunk and sparse foliage at the top, to feet high.
Bark cinnamon-red, broken into thick plates, with thin, scaly surface. Wood heavy, hard, strong, close grained, red, durable.
Buds small, globose, brown, hoary. Western Larch needles are 3-sided, while Alpine Larch needles have 4 sides. Also, Western Larch cones connect to the branch on short stalks, while Alpine Larch cones are nearly stalkless.
Uses: Western Larch is made into lumber used for framing and finishing. It's also used for pulp and firewood. Names: Occidentalis means "western," and Larix.
Commercial thinning is an intermediate harvest in immature stands, where trees have reached merchantable size, and all or part of the felled trees are extracted for useful products.
As practiced in British Columbia, commercial thinning is generally part of a clearcut silvicultural system. Crop-Tree Thinning a Year-Old Western Larch Stand: Year Res u Its. CO~1PLETED /.6i. Dennis M.

Silvicultural practices such as pre-commercial thinning (PCT) and repeated fertilization have been used successfully around the world to increase forest biomass for conventional wood products, biofuels, and carbon sequestration.

Its seeds are prized as food by many birds, including pine siskins, redpolls, and crossbills. The western larch was one ofFile Size: KB. It is a large deciduous coniferous tree reaching 30 to 60 metres (98 to ft) tall, with a trunk up to metres ( ft) diameter. The largest known western larch is feet (47 m) tall and 22 feet ( m) in circumference with a 34 feet (10 m) crown, located at Seeley Lake, Montana.
 The crown is narrow conic; the main branches are level to upswept, with the Family: Pinaceae. Our study is superimposed on the Western Larch Density Management Study (WLDMS), a western larch precommercial thinning study located in northwestern Montana, USA and established in by the USDA Forest Service (Schmidt, ).The WLDMS is replicated at four sites (i.e., blocks), which were chosen for their uniform stocking and to capture the productivity gradient of western larch Cited by: Thinning is a term used in agricultural sciences to mean the removal of some plants, or parts of plants, to make room for the growth of others but does not involve the cutting of the whole ive removal of parts of a plant such as branches, buds, or roots is typically known as pruning.
In forestry, thinning is the selective removal of trees, primarily undertaken to. It was a lack of measurement that cost the old champion Western larch its title, according to Sheri Shannon, the national Big Tree Program coordinator in Washington, D.C.
